i have seen in the autosupport that there is a bug in our netapp configuration.
Value of the option nfs.ifc.rcv.high is unexpectedly reset
The option nfs.ifc.rcv.high value might unexpectedly get reset to a previous value if it is changed by the option nfs.tcp.recvwindowsize.
The option nfs.ifc.rcv.high controls the high-water mark after which NFS level flow control takes effect. This option is also controlled by the option nfs.tcp.recvwindowsize. Changing the option nfs.tcp.recvwindowsize automatically changes the value of the option nfs.ifc.rcv.high.
However, there are some scenarios in which the option nfs.ifc.rcv.high value gets reset to a previous value if it is changed by the option nfs.tcp.recvwindowsize.
To avoid the issue, first configure the option nfs.tcp.recvwindowsize, then manually configure the option nfs.ifc.rcv.high.
Solved! SEE THE SOLUTION
